The verdict · stolen

The Flyers stole one. They lost the expected-goals battle 2.05–3.93 and won anyway.

PHI 5 · NJD 1
◆ By the ModelJul 12, 10:42 AMxG: xgboost-0.758Edited for clarityDrafted from NHL play-by-play by Backcheck's model, worded for clarity by an AI editor that may not change a number. Nobody at Backcheck was at the rink. How this works

The Flyers won 5–1 despite losing the expected-goal battle 3.93–2.05—a 66–34 split that should have meant a much closer game. D. Vladar made the difference.

The Devils controlled the shot attempts (55%, 24–20) and dominated the quality of chances (9 high-danger opportunities to 2), but converted nothing. Philadelphia was ruthless in the opposite direction: four goals came on the rush, off limited volume. The Devils generated 5 rebound opportunities and couldn't finish any of them.

D. Vladar stopped 23 of 24 shots, a 0.958 save percentage that included a perfect 100% mark on nine high-danger attempts. He saved 2.93 goals above expected—the margin between a blowout and a contest. J. Markstrom faced a smaller workload (15 saves on 19 shots) but couldn't execute: a 0.789 save percentage meant allowing 1.95 goals more than his underlying numbers suggested.

The variance was brutal for New Jersey. The club underperformed its xG by 2.9 goals, a combination of poor execution and a netminder who couldn't bail them out. Philadelphia overperformed its expected goals by 3.0 in the opposite direction, though their finishing on the rush justified some of that outperformance. Vladar simply did his job better than any metric suggested.

This wasn't the Devils playing bad hockey—they created the looks and held territorial advantage. But 0 for 9 on high-danger chances is a death sentence, even with an elite goaltender in net (he wasn't). Philadelphia won because Vladar was a wall and the Flyers converted their few chances into points, while New Jersey wasted a superior workload.

New to these numbers?

Two things happened in this game: who created the better chances, and who put the puck in the net. They are not the same thing, and this page separates them on purpose.

The one to watch is expected goals— the best single read on who deserved to win. When it disagrees with the scoreboard, that disagreement is usually the story. Nothing here is a projection; every figure is computed from this game's play-by-play. Full glossary →

xG
Expected goals. Every shot scored by how often that exact look goes in. 2.5 xG means the chances were worth about two and a half goals.
HD
High-danger chances — shots from the slot and the crease, where shots actually become goals.
Corsi
Every shot attempt, including the ones that missed or got blocked. A rough read on who had the puck.
Adj.
Score-adjusted. Teams that trail shoot more and teams that lead sit back, so this corrects the attempt count for the scoreboard.
GSAx
Goals saved above expected. A positive number means the goalie stopped more than an average goalie would have on those shots.
PDO
Shooting % plus save % — a luck gauge. It sits near 1.000 over a season, so a game far from it usually means the bounces decided it.

The read

Edited for clarity
◆ By the ModelJul 12, 10:41 AMEdited for clarityDrafted from NHL play-by-play by Backcheck's model, worded for clarity by an AI editor that may not change a number. Nobody at Backcheck was at the rink. How this works

The model projects a 2.4–2.5 game with the Devils at 51% win probability. That's a coin flip.

The Devils control territory: their 51.0% Corsi beats Philadelphia's 48.0%, meaning they're dictating pace and puck movement. But that possession advantage doesn't translate to shot quality. The Flyers' 51.0% expected goals percentage virtually matches New Jersey's 50.0%, so what the Devils win in volume, Philadelphia compensates for in efficiency.

New Jersey is running cold. Their 0.971 PDO signals snakebite on both ends—fewer goals than their play deserves, more conceded than their defense warrants. Positive regression is built in.

The forward groups are evenly talented. Philadelphia's Owen Tippett generates 0.88 expected goals per 60 minutes and has scored 19 goals on a high 12.1% shooting percentage, paired with 18 assists and 2 high-danger markers. His teammate Christian Dvorak creates at similar volume (0.81 xG/60), with 12 goals, 21 assists, and 3 high-danger tallies. New Jersey counters with Timo Meier at elite volume—1.08 xG/60, tops on the ice—accompanied by 13 goals, 15 assists, and 3 high-danger goals. Jack Hughes (0.88 xG/60) adds secondary star power: 18 goals and 17 assists, with 1 high-danger goal.

The shooting percentages reveal where regression lives. Tippett (12.1%) and Dvorak (11.2%) are operating well above average. Meier sits at 6.7%—well below. Hughes at 11.5% joins the elevated tier. If Tippett and Dvorak regress downward while Meier regresses upward—the likeliest path—the Flyers lose scoring depth as the Devils' star gains it. That's a material shift in a game this close.

Neither team has seized an edge. This is what a true pick'em looks like.
